A History of Commercial Plant Growth Regulators in Apple Production

Impacts of plant growth regulators and culture media on in vitro propagation of three apple (Malus domestica Borkh.) rootstocks

Apple is one of the most important temperate-zone fruit trees in the world. Micropropagation of apple scion and rootstocks is an important method of rapid production of healthy and disease-free plants. In this research, in vitro propagation of three apple roottocks including Azayesh-Esfahan, Morabbaee-Mashhad and M9 was investigated. Shoot proliferation carried out in two basal media (MS and WP...

Changes in Growth and Trigonelline/Mucilage Production of Fenugreek (Trigonella foenum- graecum L.) under Plant Growth Regulators Application

Background: Fenugreek (Trigonella foenum - graecum L.) is an annual medicinal plant belongs to the legume family and has anti-diabetic, anti-fertility, anticancer, anti-microbial, anti-parasitic and hypocholesterolaemic effects. Objective: Evaluation of growth and trigonelline /mucilage content in fenugreek under application of plant growth regulators (PGR). Methods: The experiment was conduc...

the effect of plant growth regulators on growth and production of β-carotene in dunaliella salina

Plant Growth Regulators

Plant growth regulators are hormone-like chemicals that occur naturally in plants, and play a central role in their growth and development. Five major classes of plant growth regulators have been identified as plant hormones, but scientists believe that there are more waiting to be discovered. The five growth hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Collec...

Tissue Culture and Production of Volatile Secondary Metabolites from Callus of Stevia rebaudiana at Different Combination of Plant Growth Regulators

 Stevia rebaudiana Bert (Asteraceae) is herbaceous plant with sweet leaves, which are the source of sweetener products. The present study focuses on effects of different combination of plant growth regulators on callus induction, callus cell growth and regeneration and volatile constituents from callus of stevia in tissue culture condition. The results of present study showed callus formation p...
